Why are we here?
• Orthopaedic injuries compromise 1 in 5 of all visitsto emergency rooms
• In many cases, appropriate initial managementcan have a significant impact on outcome• Compartment syndrome, open fractures, pelvis injuries
Terminology Review
• Fractures = Broken Bones
• Dislocation = Joint disruption
• Sprain = When a ligament is torn or stretchedbeyond normal range– Huge component of traumatic injuries– Often have missed fractures
• Strain = Muscle is stretched beyond normal range
Physical Exam Terminology
• Deformity
• Tenderness
• Guarding
• Swelling
• Bruising
• Crepitus
• False Motion
• Locked Joint

Fractures
• What bone is broken?
• Open vs. closed?
• Displaced or non-displaced?
• Isolated injury or polytrauma?
• Associated conditions
– Vascular Injury
– Neurologic Injury
– Compartment syndrome
Open Fractures
• Often scarier than they really are
• Ok to allow/push exposed boneback in if compromised skin
• Usually reduce with gentlelongitudinal traction
• Put sterile compression dressingson and splint
• Still at risk for compartmentsyndrome
Dislocations
• What joint is it?
– Acromioclavicular vs.glenohumeral
– Shoulder and hip mostcommon
• Is it stable or unstable
– Did it pop out again?
• Distal neurovascular status

Hip Dislocations
• Traumatic posterior hip dislocations are highenergy injuries (Not grandma’s total hip)
• Associated injuries are common• Outcome is highly dependant on time to
reduction, associated injuries and post-reductionmanagement
• Unsatisfactory results can be expected in up to50% of patients– Dreinhofer, JBJS, 1994, Yang, Clin Orthop, 1991
• Treatment is directed to the avoidance ofcomplications
• Due to mechanism, concomitant injuries are therule
• Up to 95% require inpatient care– Suraci, J Trauma, 1985
• Ipsilateral injuries include
– Pelvic and acetabular fractures
– Femoral head, neck or shaft fractures
– Patella fracture, knee ligament ruptures
and dislocations
– Sciatic nerve injury
Hip Dislocation AssociatedInjuries
Pelvic Fractures and PelvicBinders
• Patterns of Pelvic Fracture
– Anterior to Posterior (The Open Book Type)
– Lateral Compression
– Vertical Shear
• Analogy
– “Life saver never breaks in one spot”.
– Pelvis rarely breaks in one location.
• Open Book benefit with Binders and tapingfeet and legs to prevent external rotation.

How Binders Work
• The pelvic binder is used tosplint the bony pelvis inopen book injuries. Thebinder splints the bonyfracture, approximatingbone ends and reducinglow-pressure bleeding frombone ends and disruptedveins.
• http://www.trauma.org/index.php/main/article/657/
Physical Exam for PelvisStability
• In training we all learn pelvic “rock”
– Squeeze Together and Push Down-Be Careful
• PEARL for Recognizing Open Book Pelvis
– Feel your pubic symphysis, just below your beltbuckle. Normal gap is one finger or 1cm.
– Open book pelvis is tender at the symphysis withswelling and a gap greater than your finger width.
Applying a Pelvic Binder
• The binder should be placed over thegreater trochanters, NOT the iliac crests.
• The binder will not control arterialhemorrhage. Patients who do not improvehemodynamically following application ofthe pelvic binder may require urgentangio-embolization or operativeintervention.

Pelvic Binders Types
• The manufacturer isless relevant thanapplying correctly.
• Locally you see T-Pod and SAM Splints.
• A sheet can do thejob with towel clips.Nothing fancy orexpensive buteffective.
Pelvic Binder Key Points• Apply with just enough force to close
pelvis disruption. Too much pressure canover-reduce the pelvis. If left on pressurebreakdown can occur, important not to foldextra material (trim to fit on T-Pod andsheets.)
• Proper placement allows access forembolization and laparotomy. Sheetbinders are great as you can just cut holesif needed.
Femur Fractures
• Femur Fractures
• Locations- Proximal third, middle half,distal third
• Physiology of blood Loss 1000-2000 ccblood loss per CLOSED fx
• Closed versus Open
• Unilateral vs Bilateral

Types of Pre-Hospital FemurTraction Splints
• Thomas Splints- half circle under proximal thigh
• Hare Splints-about quarter of a circle under the proximal thigh
• BOTH Thomas and Hare require the leg to be lifted, only provideunilateral traction, and have non-quantifiable traction
Femur Traction SplintIndications
• Middle half without Pelvic/knee/lower leg fractures.
(Sager has an application for proximal/hip fractures)
• Traction relaxes the spasm of muscles that your bodydoes to stabilize fractures.
• Lengthening muscles compresses around the fracturesite and diminishes the potential space for blood tocollect.
• Maintain proper alignment- Length and Rotation
• Prevents further soft tissue injury by fracture
Sager Splints
• Do not have to lift leg.• Made unilateral or
bilateral.• Quantifiable dynamic
traction
Unilateral
Bilateral

Kendrick’s Traction Device
• KTD- Kendricks tractiondevice(Now OPD)
• Very compact, does notlift leg
• Fits on lateral thigh• Non-quantifiable traction• Does not control rotation,
important to tape feet
CT-6 Carbon Traction LegSplint
• CT-6- Very compact, veryrigid as carbon fiber (versusaluminum KTD)
• Has 4:1 pulley for tractionapplication, and has non-quantifiable traction
Application technique
• Application technique. Compare extremities inunilateral fractures, for length and rotation.
– IF unilateral,you can apply traction up till about thesame length as non-injured leg. This may have a fewadjustments as Spasm relaxes.
TAPE/BIND feet to stop rotation during handling/transport.
• Measuring Traction. Apply TO RELIEF.
Sager is only one with quantifiable & dynamic andbilateral traction. Focus on relieving the spasm, notthe numbers or pounds of traction on a splint.

Ankle Strap malposition causingRotation.
Good position. Straps are oneach side/malleoli of ankle. Thefeet and legs are tied together
Adjustable for the Ankle Sizefrom Cankle(Calf/Ankle) to Kids

Skin Traction in the Hospital“Bucks”
Used for inpatient Hip/Proximal Femur Fractures
Friction Applied to skin & soft tissues
• Provides light, temporary pull
– 5-10 lbs
• KEY POINT
– In Pre-Hospital training we hear “Don’t Put Traction onProximal Femur/ Hip Fractures”. (Sager says OK)
– I am telling you we put traction on these in the hospital.So if you accidentally apply traction to a proximal femurfracture, don’t panic or worry.
Skeletal Traction
• Direct, longitudinal pull appliedto bone with use of a tractionbow
– Steinmann pin
– Kirschner wire
– Tongs
• Strong, steady traction force
– 15 - 40 lbs (depends on pinsize and location of pin)
• Risk for:
– Pin track infection
– Osteomyelitis
Skeletal Traction Sites
• Skull for Cervical
• Pelvis
• Distal End ofFemur
• Proximal Tibia
• Calcaneus

Splint’s Indications
• Fractures
• Sprains/Dislocations
• Joint infections
• Tenosynovitis
• Acute arthritis / gout
• Lacerations over joints
• Puncture wounds and animal bites of thehands or feet
Proper Application• Materials-Plaster / Fiberglass / SAM type
• All splints should have a minimum of twolayers of padding applied at the skin, eventhe “prepadded” splint materials/packages.
• Cover all edges. When trimmingprepadded, the padding can be pulledover ends after cut from package.
• Do not fold in “corners”, they causepressure points and breakdown.
• Too Hot Water can splint reaction/curinghotter and cause burns.
Proper Application continued• Straighten out with gentle longitudinal traction
while splinting.
– To allow splinting in “normal position”
• Splint in near anatomic position as possibleprotects nerves and vessels.
• Don’t feed injured patients

Examples of Splint Types(there are many more!)
Upper Extremity
• Elbow/Forearm– Long Arm Posterior
– Double Sugar – Tong
– Coaptation (stirrup)
• Forearm/Wrist– Volar Forearm / Cockup
– Sugar – Tong/ Reverse
• Hand/Fingers– Ulnar Gutter
– Radial Gutter
– Thumb Spica
– Finger Splints
• Lower Extremity
• Knee– Knee Immobilizer / Bledsoe
– Bulky Jones
– Posterior Knee Splint
• Ankle– Posterior Ankle
– Stirrup
– Three-sided (Posterior andStirrup)
• Foot– Hard Shoe
Coaptation
• Indicated for humeralshaft fractures.
• A sugar tong that startsin armpit and wrapsOVER the shoulder.
• PEARL: Combine withsugar tong on theforearm for excellentcontrol ofhumerus/elbow/forearminjuries.
Reverse Sugar Tong• Controls wrist and elbow
flexion and forearm rotation.
• Often have “extra” whenwrapping sugar tongs onforearms and ankles. Cutthrough the extra/loop andoverlap to avoid pressurepoints.
• As seen in Sugar Tongsplint photo next.

Sugar Tong
• Not as commonly/correctly ordered but veryeffective.
• Loop End placed at handafter a notch is cut to sit inthe thumb web space.
• Then two ends overlappedat elbow avoiding folds orcorners.
Three Sided Ankle Splint
• Most stable anklesplint construct as itcontrols rotation andflexion/extension atankle.
• If reducing fracture/dislocation of ankle,use this for bestcontrol.

Compartment Syndrome
• Compartment syndrome isan important clinical entity
• Condition in whichintramuscular pressurewithin an enclosed fascialspace exceeds capillaryblood pressure
• If untreated, damage totissues can be irreversible
• Approximately 40% occurin fractures of the tibialshaft with an incidence of1 to 10%.
• Blick, JBJS 1986
Importance of CompartmentSyndrome
• Sequelae of compartment syndromecan be devastating– Volkmann’s Contractures– Irreversible ischemia– RSD/CRPS– Sepsis– Renal Failure– Death
• Missed diagnosis or delay intreatment is the #1 reason forlawsuits involving Orthopedicsurgeons with average settlement of$280K
• Templeman, Orthop Trans1994, Bhattacharyya, JBJS,2004
• Complication rates of early vs. latefasciotomy are 4.5% vs. 54%
• Williams, Surgery, 1997,Sheridan, JBJS, 1976
Etiology• There are a multitude of causes of compartment
syndrome and its etiology is probablymultifactorial
1- A decrease in size of the compartment
2- An increase in the content of the compartment
3- Swelling due to abnormal muscle chroniccompartment syndrome
11/9/2016
15
Etiology
• Decreased Compartment size
– Constrictive dressings or casts
– Tight closure of fascial defects
– Traction/reduction of fractures
– Thermal injury
– Crush Injury
Etiology
• Increased Contents
– Hemorrhage• Bleeding disorders
• Anticoagulanttherapy/overdose
• Arterial laceration
– Hemorrhage plusedema
• Fractures
• Soft tissue crushinjuries
Etiology
• Increased Contents
– Edema
• Postischemic swelling from injury, arterialthrombus, or embolism
• Vascular reconstruction and bypass surgery
• Replantation
• Prolonged tourniquet time
• Prolonged immobilization (drug OD, entrapment)
• Snake bite/invenomation
11/9/2016
16
Common Causes• Fracture
• Crush
• Arterial Injury
• Limb Compression– with or without
hypotension
– constrictivecast/bandages
• Burns
Diagnosis
• Unreliable, uncooperative, or comatosepatients
– Physical Exam unreliable
– Measure compartment pressures
Diagnosis• Differs for alert or comatose patients, adults
or children
• Alert/cooperative patients can assess 6 P’s
– Pain out of proportion
– Pain on passive stretch
– Pressure to palpation (compartment not soft)
– Paralysis (due to pain or nerve injury)
– Paresthesia (occurs early)– Pulselessness (Often Very Late)

17
Diagnosis• Any compartment can get compartment
syndrome• Upper Extremity
– Deltoid– Scapula– Arm
• Anterior• posterior
– Forearm• Dorsal• mobile wad• deep volar• superficial volar
• Upper Extremity
– Hand
• 10 compartments
• Abdomen
• Pelvis
– Iliacus
– Gluteal
• Lower Extremity
– Thigh
• anterior,posterior, medial
– Calf
• Anterior
• Lateral
• Superficialposterior
• Deep Posterior
11/9/2016
18
• Lower Extremity
– Foot• 9 compartments
– Medial
– Superficial
– Lateral
– Adductor
– 4 interosseous
– Calcaneal
Treatment
• First Aid to hypoxic cells
– Keep patient normotensive
– Remove constricting bandages
– Elevate limb to heart height
– O2 administration to keep fully oxygenated
Treatment• Post fasciotomy
– elevate to heart
– delayed primary closure
• at one sitting
• gradually using skin stretchingtechniques
– shoelace
– subcuticular technique (i.e.prolene)
– mechanical wound closuredevices
• Wound Vac-closed system
– Skin grafting 5-7 days later ifclosure not possible

Outcomes
• Good if treated early– 4% Complication rate
– Some complaints of scarring
– Pain with exercise
• Untreated Compartment
Syndrome– Volkmann’s Ischemic Contracture
• paralysis and contracture
– Late fasciotomy (after 48 hrs)• Often not helpful
• may be more injurious - open, necrotic muscle
• Amputation rate is high (5/5 patients, Finklestein)
Compartment SyndromeSummary
• Do not miss compartment syndrome
• If you think CS, you should do something about it
– rule it in or out
• Act promptly for thepatients’ best interest
Don’t elevate, don’t refrigerate, don’t hesitate, OPERATE
External Fixators
• Provide stability to fractures and/orligamentous injuries.
• Recently, they were used for definitivetreatment
• Significant improvements in surgical implants(plates, screws, nails) have made externalfixators temporary in their uses.
• There are indications for definitive treatment.A specialty exists for “fine wire” or Illizarovmethod for the treatment of malunions,nonunions, and congenital/hereditary skeletalmalformations.

External Fixation
• Pins / wires connected byclamps to bars creating arigid external frame
• Uses:– Open comminuted
fractures
– Extensive soft tissuedamage
– Multiple trauma
– High risk of infection
– Closed fracture with difficultpositioning or length
– Surgical joint fusion orbone grafting
External Fixation: AdvantagesImmediate stabilization
• Rigid fixation w /compression
• Increased comfort
• Ability to observe softtissue / wounds
• Facilitates vessel /tissue reconstruction
• Maintains motion ofadjacent joints
• Fewer complications ofimmobility
Wound Vacs® & their OrthopaedicUse
• Used in OrthopaedicCases where weexpect discharge andexudate
• Fasciotomies,Trauma Wounds,Edema fromTrauma/FluidResuscitation
• Split Thickness SkinGrafts (STSG)
11/9/2016
21
Wound Vacs®• Machine Settings• More Commonly used
setting for our facility iscontinuous 125mm Hg.
• Commonly dressingsare changed 2-3dayson the floor by PT or inOR with repeat I&D’s.
• The machines have aleak detection screenmaking it easier totrouble shoot a leakingvac.
Wound Vacs® Physiology
• Works to control drainage,discharge, exudate, decreasewound volume, and keep clean& dry.
• Apply vac foam directly towound, overlap with occlusivedressing, and the “Trac Pad”connector to machine.
• Not to be applied directly overtendons or neuro-vascularstructures. These structurescan be protected with a non-adherent dressing like “telfa” orthere is a special white foam toprotect these tissues.
Rib Fractures and Flail Chests
From
“Nobody fixes those, that’s crazy!”
To
“People don’t do well with those fractures, whatcan we do”

Rib Fractures and Behind Them
Multiple Rib Fractures
Some studies waited until patients could notwean from ventilators and were alreadystressed with diminished physiologicreserves. It was hard to determine whowould not do well and need fixation.

Early Intervention at RenownResults: No case of hardware failure, hardware prominence,wound infection, or nonunion was reported. Operatively treatedpatients had shorter intensive care unit stays (7.59 vs. 9.68days, P = 0.018), decreased ventilator requirements (4.14 vs.9.68 days, P = 0.007), shorter hospital LOS (11.9 vs. 19.0 days,P = 0.006), fewer tracheostomies (4.55% vs. 39.29%, P =0.042), less pneumonia (4.55% vs. 25%, P = 0.047), less needfor reintubation (4.55% vs. 17.86%, P = 0.34), and decreasedhome oxygen requirements (4.55% vs. 17.86%, P = 0.034).“Early Surgical Stabilization of Flail Chest With Locked Plate Fixation” Althausen,Peter L MD, MBA*; Shannon, Steven BS†; Watts, Chad BS†; Thomas, Kenneth MD*;Bain, Martin A MD, FACS‡; Coll, Daniel P-AC, MHS§; O'Mara, Timothy J MD*; Bray,Timothy J MD*

DVTs in Orthopaedics
• Thromboses start at the time of injury/surgery and can form atanytime after, until fully recovered.
• Before Prophylaxis- Ortho Joint Replacement
– DVT rates 30-50+%
– Mortality Rate of Total Joints Prophylaxis w/PE 3-6%
• Even on Prophylaxis- DVT Rates of 1-4%
The answer seems obvious, but there is very little data todocument that prophylaxis against DVT actually prevents fatal PE
Other Emboli In OrthopaedicsFat Emboli Syndrome
• Fat emboli occurs in up to 90% of all patients with severeinjuries from fracture of pelvis, long bones, trauma to softtissue, burns, and fatty liver.
• Only 10% of these patients with fat emboli are symptomatic.
• The risk is believed to be reduced with early immobilzationand early surgical intervention.
• Symptoms can occur 1-3 days from injury and may include:– Pulmonary
– Neurologic
– Dermatologic
– Hematologic
